Answer Key

Keeping your passphrase private

Section A: Quick Questions

A — Say no and keep it secret, even from a best friend

A — A parent or carer you trust

B — Cover the keyboard or wait until no one is watching

A — In your memory, or shared only with a trusted parent or carer

B — Do not send it in a message, and ask a trusted adult for help

Section B: Match the Pairs

keep it private → Your passphrase is a secret, so you do not tell it to friends, even your best friend.

share with a parent or carer → The only person you may tell your passphrase to is a parent or carer you trust.

Cover the keyboard with your hand so no one can watch you type your passphrase. → cover_keyboard()

Do not leave your passphrase on a note stuck by the screen where others can read it. → note_by_screen = false

send(friend, "My passphrase is purple-frog-tent") → Sending your passphrase in a message to a friend shares your secret. The message could be seen or passed on.

stick_note(screen, passphrase) → Sticking your passphrase on a note by the screen lets anyone who walks past read it.

Section C: Definitions

keep it private — Your passphrase is a secret. Do not tell friends, type it where others can watch, or put it in a message. Only share it with a parent or carer you trust.

Section D: Fill in the Blanks

tellFriends = false

IF person = "friend" THEN
  keepPrivate(passphrase)
END IF

IF who = "parent" THEN
  share(passphrase)
END IF

IF peopleWatching = true THEN
  coverKeyboard()
END IF

IF noteByScreen = true THEN
  throwAway(note)
END IF

Section E: Spot the Error

A — Your passphrase is a secret, so you must not share it with friends. The first line should be share_with_friends = False.

C — A friend is not on the trusted list, so ok should be False. Using 'not in' would make it True and let a friend get the passphrase. It should be: ok = who_asks in trusted.

C — You should cover the keyboard so nobody can watch you type your passphrase. Uncovering it lets others see. The line should be cover_keyboard().

B — A note stuck by the screen lets anyone read your passphrase, so it is not safe. It should be note_on_screen = False.

D — Setting nearby to False just assumes nobody is watching without checking. You need to look around again before typing your passphrase: nearby = look_around().
